SX/SA28

Designed in Power & Flexibility

The SX/SA28, dual eight-inch subwoofer provides power and punch equal to most single 12 inch subs in a cabinet that is 2/3 the volume, making it very easy to integrate into any project. Large ports insure that this forceful bass is never marred by any chuffing or fluttering noises.

The SX/SA28, dual eight-inch subwoofer provides power and punch equal to most single 12 inch subs in a cabinet that is 2/3 the volume, making it very easy to integrate into any project. Large ports insure that this forceful bass is never marred by any chuffing or fluttering noises.

Sixteen, M10 Universal Mounting Points allow the SX/SA28 to be flown using M10 eyebolts, while the recessed handles, top-mounted pole adapter and available casters make portable use easy and practical.

The optional SA1250 power amplifier precisely matches the power needs of the SA28, provides optimal damping of the woofer and has factory optimized, multi-band limiting. The built-in amp eliminates the need for additional rack space and speaker cable runs, making adding a subwoofer to existing installs as simple as plugging it into power and running a signal to it.

Controlled via RHAON II, the SA1250’s built-in DSP has eight, fully parametric EQ filters, high and low shelf and high and low pass filters and up to 340 ms. of delay. All easily accessed via a Windows computer running RHAON II.

The SA28-RD adds Dante digital signal distribution capability including AES67 compatibility and network redundancy.
